Brief Description

The KTU1120 provides four conducting paths with overvoltage

protection (OVP) for USB Type-C, CC, and SBU

signals. Once an over-voltage event is detected, it will

shut down all paths to protect circuits in system side, like

PD controller from damage.

All the SBU and CC switches have very low oncapacitance

for broad bandwidth to allow high-speed

signal passing through without loss. The CC1/2 switches

have low on-resistance for passing VCONN power up to

1.25A.

During dead battery conditions, internal 5.1kΩ resistors

automatically pull down on CC1/2 to ensure that the upstream

source provides 5V on VBUS.

The KTU1120 is packaged in RoHS and Green

compliant 16-bump WLCSP 1.7mmx1.7mm package.

Applications

• Notebook PCs, Netbooks, Tablets, Monitors, TVs

• Gaming Devices, Set-Top Boxes, Networking
